Best way to set host key in Modular Inputs

Champion

I am building a Modular Input but would like to set the host behind the scene. I know that I can use Scheme Default but that sets the default for all stanza.


[poll://Server1]
port=4532
comString=helloworld
id=1.23.22.15.3
#I want the value of poll to automagicly set value for host when the user goes through the Manager.
host=Server1

I know I could use a transform to set the Server1 host value during indexing, but there is got to be a better way with modular inputs. I don't want the user to retype Server1 Manager screen.

How would I accomplish this with the <manager>.xml, in a introspection, or in my .py script?

You could use XML streaming mode (http://docs.splunk.com/Documentation/Splunk/latest/AdvancedDev/ModInputsStream) and then set the host value on each event in your python script, for example:

print "<stream><event><data>09/08/2011 14:01:59.0398 event_status="(0)The operation completed successfully."</data><host>yourhost</host></event></stream>"

You can get the stanza name by parsing the input configuration (http://docs.splunk.com/Documentation/Splunk/latest/AdvancedDev/ModInputsScripts see "Example code reading XML configuration") and use this value in the host attribute.

Of course you can use the host key from inputs.conf by parsing the XML. See an example here:
http://docs.splunk.com/Documentation/Splunk/latest/AdvancedDev/ModInputsExample

After parsing the XML, just replace

<host>yourhost</host>

from my streaming sample above to something like

print "<stream><event><data>09/08/2011 14:01:59.0398 event_status="(0)The operation completed successfully."</data>%s</host></event></stream>" % config['host']

I was hoping to set the create the host key parsing by the XML feed from the Inputs Manager and place it in the inputs.conf.
